1APM X-Gene SoC Ethernet nodes 2 3Ethernet nodes are defined to describe on-chip ethernet interfaces in 4APM X-Gene SoC. 5 6Required properties for all the ethernet interfaces: 7- compatible: Should state binding information from the following list, 8 - "apm,xgene-enet": RGMII based 1G interface 9 - "apm,xgene1-sgenet": SGMII based 1G interface 10 - "apm,xgene1-xgenet": XFI based 10G interface 11- reg: Address and length of the register set for the device. It contains the 12 information of registers in the same order as described by reg-names 13- reg-names: Should contain the register set names 14 - "enet_csr": Ethernet control and status register address space 15 - "ring_csr": Descriptor ring control and status register address space 16 - "ring_cmd": Descriptor ring command register address space 17- interrupts: Two interrupt specifiers can be specified. 18 - First is the Rx interrupt. This irq is mandatory. 19 - Second is the Tx completion interrupt. 20 This is supported only on SGMII based 1GbE and 10GbE interfaces. 21- port-id: Port number (0 or 1) 22- clocks: Reference to the clock entry. 23- local-mac-address: MAC address assigned to this device 24- phy-connection-type: Interface type between ethernet device and PHY device 25 26Required properties for ethernet interfaces that have external PHY: 27- phy-handle: Reference to a PHY node connected to this device 28 29- mdio: Device tree subnode with the following required properties: 30 - compatible: Must be "apm,xgene-mdio". 31 - #address-cells: Must be <1>. 32 - #size-cells: Must be <0>. 33 34 For the phy on the mdio bus, there must be a node with the following fields: 35 - compatible: PHY identifier. Please refer ./phy.txt for the format. 36 - reg: The ID number for the phy. 37 38Optional properties: 39- status: Should be "ok" or "disabled" for enabled/disabled. Default is "ok". 40 41Example: 42 menetclk: menetclk { 43 compatible = "apm,xgene-device-clock"; 44 clock-output-names = "menetclk"; 45 status = "ok"; 46 }; 47 48 menet: ethernet@17020000 { 49 compatible = "apm,xgene-enet"; 50 status = "disabled"; 51 reg = <0x0 0x17020000 0x0 0xd100>, 52 <0x0 0X17030000 0x0 0X400>, 53 <0x0 0X10000000 0x0 0X200>; 54 reg-names = "enet_csr", "ring_csr", "ring_cmd"; 55 interrupts = <0x0 0x3c 0x4>; 56 port-id = <0>; 57 clocks = <&menetclk 0>; 58 local-mac-address = [00 01 73 00 00 01]; 59 phy-connection-type = "rgmii"; 60 phy-handle = <&menetphy>; 61 mdio { 62 compatible = "apm,xgene-mdio"; 63 #address-cells = <1>; 64 #size-cells = <0>; 65 menetphy: menetphy@3 { 66 compatible = "ethernet-phy-id001c.c915"; 67 reg = <0x3>; 68 }; 69 70 }; 71 }; 72 73/* Board-specific peripheral configurations */ 74&menet { 75 status = "ok"; 76}; 77
